Slice the chicken breast into thin bite-sized strips.
In a small bowl, whisk together the cumin, coriander, turmeric, garlic powder, sea salt, and black pepper.
Toss the chicken strips in the spice blend until evenly coated.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sauté for 6-8 minutes until golden brown and cooked through.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion.
In a small ramekin, stir together the Greek yogurt and lemon juice to create a smooth sauce.
Place the warm cooked basmati rice in the center of a bowl.
Arrange the spiced chicken on one side of the rice and the fresh cucumber, tomato, and onion salad on the other side.
Drizzle the lemon-yogurt sauce over the entire bowl and serve immediately.
